Fledgling Camp — first-time camper introduction to overnight camp

Fledgling Camp is the perfect introduction to overnight adventures—but it's not just for first-time campers. Whether it's your child's very first night away from home or they've experienced camp before, this safe, fun-filled stay lets kids discover nature, make friends, and try hands-on science. Join small, age-appropriate groups for hikes and activities, building friendships and confidence. Hosted at ONSC's Main Campus, Fledgling Camp is the perfect way for kids to start—or continue—their love of nature, science, and overnight adventures.

Independence, growth & leadership

Chaperones — interview and background check required

We have a limited number of free tickets for parent chaperones. We will need at least one male and one female chaperone for each age group with a maximum of 6 total chaperones. We strive to assign chaperones to field groups that don't include their own child(ren), to allow all students an authentic feeling of 'camp independence.' However, exceptions are made on a case-by-case basis. An interview and background check are required to become a chaperone.
